FRANK L. ANTTILA AND AUGUST I. LILIUS, .OF LOWELL, MASSACHUSETTS.

PAPER AND TWINE CUTTER.

Application filed December 11,1913.

To all whom it may concern:

Be it known that we, FRANK L. ANTTILA and AUGUs'r I. LILIUs, subjects-ofthe Czar of Russia, residing at Lowell, in the county of Middlesex andState of Massachusetts, have invented new and useful Improvements inPaper and Twine Cutters, of which the following is a specification.

This invention relates to new and useful improvements in paper and twinecutters and particularly to those adapted for cutting envelops.

The object of the invention is to provide a simple, inexpensive cutterwhich may be carried in the pocket or placed upon the end of a pencil.

The invention consists in the combination and arrangement of partswhereby the above object and certain other objects hereinafter appearingmay be attained, as set forth in the following specification andparticularly pointed out in the claims.

Referring to the drawings: Figure 1 is an enlarged front elevation of adevice embodying my invention. Fig. 2 is a longitudinal sectionalelevation taken on line 22 of Fig. 1. Fig. 3 is a section taken on line33 of Fig. 1 and viewed in the direction of the arrows on said line.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 5 is a holder provided with a groove 6 extendingtransversely thereof adjacent the upper end, while a groove 7 extendsfrom said groove 6 to the rear face of the holder. A cutter blade 8 isadjustably mounted in a recess 9 formed in said holder, said recessextending longitudinally of said holder for a portion of its length tothe transverse groove 6.

The sides of the recess 9 constitute guides for the cutter blade 8permitting said blade to be moved toward and away from the groove 6. Thecutting edge 10 of said blade is adapted to project into said groove 6and substantially engages the periphery of a grooved roller 11 mountedin a recess 12 formed upon the opposite side of the groove 6, saidroller being arranged to rotate in a plane containing the cutting edgeof said blade, in conjunction therewith and upon a stud 13.

A plate 14: is secured to the front of said holder and adapted toinclose said blade within the recess 9, while a screw 15 extends throughsaid plate and into engagement Specification of Letters Patent.

with said holder. Means are also provided to clamp said cutter blade insaid recess, said means consisting of a piece of resilient material 16,preferably of rubber, which is inserted between said blade and saidplate 14 and as said plate is clamped against said holder by the screw15 said rubber will be compressed and thereby firmly maintain the bladein its proper relation to the roller 11.

'To adjust the cutter blade 8 relatively to the roller 11 I haveprovided a cam 17 which is pivotally mounted on said screw 15 andengages the lower end of said blade, said cam projecting outwardlybetween the plate 14 and said holder and into a position to be engagedby the finger of the user, and may, upon the releasing of said screw, berotated to force said blade toward said roller 11, thus taking up forany wear which may be caused by the grinding or sharpening of saidblade.

The holder 5 is provided at its lower end with a recess 18 which may, ifdesired, receive the end of a lead pencil and be carried aroundtherewith, while the upper end is provided with an eraser.

To cut an envelop or a piece of paper with the device hereinbeforespecifically described the edge of said'envelop is inserted in thegroove 6 between the cutting edge of said cutter blade and said rollerand drawn therebetween, thus cutting off the portion of said envelopbetween said cutting edge and the inner wall of said groove.

To sever a piece of twine with said device the twine is inserted in thegroove 7 extending transversely of the cutting edge 10, said groove 7extending through the holder 5 to a point substantially beyond the axisof the pivot for the roller 11, thus permitting said twine to be engagedby said roller and forced thereby against said cutting edge whereuponsaid twine will be severed.

Having thus described my invention, what I claim and desire by LettersPatent to secure is:

1. A device of the class described having, in combination, a holderhaving a groove extending transversely of one end, a stationary cutterblade movably arranged in said holder with its cutting edge projectinginto said groove, a rotatable cam adapted to move said blade toward saidgroove, and a roller mounted to rotate in conjunction with the cuttingedge of said blade.

2. A device of the class described having,

lOO

in combination, a holder, a stationary cutter mounted in said holder, acamarranged be-,

taining said cutting edge, said holder hav- 7 ing a groove extendingtransversely of the cutting edge of said cutter blade to'a pointsubstantially beyond the center of said roller, said groove alining withthe contacting portions of said cutter blade and said roller.

A device of the class described having,

in combination, a holder provided with 'a groove extending transverselythereof, acuttcr blade movably arranged in said holder with its cuttingedge projecting into said groove, and a camadapted to adjust saidcutterblade relatively to said groove.

4. A device of the classdescribed' having,

a holder provided with-a in combination, groove extending transverselythereof and a recess arranged longitudinally of said holder'and'openinginto said groove, a cutter blade adapted to adjustably fitsaid re cess w th its cutting edge projecting into 7 same toward saidroller.

said groove, a roller arranged in said holder to rotate inconjunctionwith the cutting edge of said blade,a' plate adapted toinclosesaid cutter within said recess, a screw to secure said plateto'said holder, and a cam pivoted on said screw adapted to beeperated toengage said cutter and 'move the 5. A device of the classdescribedhaving,

in combination, a holder provided with groove extending transverselyacross "one end, an-adjustable cutter blade mountedin a 7 recess formedin said holder, the 'cutting edge of said blade projecting into saidgroove, "a platesecured to said holder over said cutter-,bladeyand apiece of resilient material interposed between said" plate and saidcutter blade adapted to position said 45 blade'relatively'tosaid'roller. p 7 In testi-mony whereof we have hereunto set our hands inpresence or two subscribing witnesses.
